Assorted ramblings from the developer

Overhead Pass

Here's an example of the HF+ receiving the NOAA 18 APT weather satellite, the antenna is a log periodic covering 130 MHz to 1.3 GHz. The HF+ is very sensitive and very quiet - no mixer products, spurs, or artifacts at all.

Low Angle Pass

Here's an image from NOAA 18 but a moch lower angle - 13 degrees. You see noise on the image, but nethertheless an excellent copy.

The new website (that's this one) is almost ready - still testing but looking good. Sadly the old skins I used on DNN8 were deemed to not be secure, the company I purchased them from did nothing about this, so I bought news skines from Mandeeps.com and a new DNN system with DNN 9 was installed on a big DoDaddy farm.

LimeSDR TransmittingPosted 4 months agoI spent a day working on transmit support for the LimeSDR. This is by no means finished, but I'm able to say that it works. I have a few problems,
Big spur at 0Hz, probably generated by a bad software mixer,
Noise bursts when switching from receive to transmit.
The above are down to my own software, so I'll give myself a good kicking sometime and get this fixed later in 2017 or early 2018.
Here we see the Upper Sideband (USB) signal as received with an Airspy HF+.
And here's the TX panel from SDR Console.
